Radios are popular with truckers and security guards, as people of these professions need to constantly keep in touch with each other. The use of mobile communication in such cases is not advisable due to the high cost of a minute of conversation. Using modern walkie-talkies, you can talk to each other without interruption for an unlimited amount of time.
Instructions
Step 1
Most of the radios from the world's leading manufacturers have a range of about a kilometer, which allows security guards to talk with each other when guarding an object. Sooner or later, every person using a walkie-talkie has a desire to increase its range. There are several ways to fulfill this desire, for example, if you want to increase the range of your walkie-talkie, replace the conventional helical antenna with a special four-wave rod, which you can buy in almost every market.
Step 2
You can also use a long piece of coaxial cable as an antenna, which can significantly amplify the signal. Then adjust the frequency of the walkie-talkie so that it sends the signal as far as possible.
Step 3
The range of the antenna depends on the power of the output path. Choose the optimal frequencies for signal transmission, remembering that closer to the edges of the operating range, many characteristics of the radio for truckers, such as sensitivity and power, are significantly degraded. That is why the antenna is tuned to the middle of the frequency range as standard. That is, if your radio transmits a signal in the range from 136-174 MHz, then it will show the greatest range at a frequency of 155 MHz.
Step 4
Use only well-charged batteries, as the power output depends on the power supply. Therefore, if you are going to use the walkie-talkie for a long time, always carry a spare battery with you. Also, if you need to increase the signal transmission range of your midland walkie-talkie for a communication session, if possible, use the hills on the ground.
Step 5
A well-functioning walkie-talkie will allow you to keep in touch with your work colleague and, in case of an unforeseen situation, promptly come to his aid. At the moment, the most popular manufacturers of walkie-talkies are Midland and Motorola. Each of these companies provides the widest range of different digital and electronic products from conventional walkie-talkies to multi-functional radios.
